On a flat lattice, atoms can easily move around from site to site. However, in a tilted lattice, the atoms would have to work against gravity.
However, these molecules can also cause collateral damage to healthy tissue around the infection site:
or site of damage in the structure of DNA, called 5-chlorocytosine (5clc) in the inflamed tissues of mice infected with the pathogen Helicobacter hepaticus.
the researchers first placed the 5clc lesion at a specific site within the genome of a bacterial virus. They then replicated the virus within the cell.
when triggered by infection, fires hypochlorous acid at the site, damaging cytosines in the DNA of the surrounding healthy tissue.
The former have a shell that is bonded directly to the core, but yolk-shell particles feature a void between the two equivalent to where the white of an egg would be.
the aluminum core continuously shrinks to become a 30-nm-across olk, which shows that small ions can get through the shell.
This research outcome potentially allows for great flexibility in the design and optimization of electronic and optoelectronic devices like solar panels and telecommunication lasers.

#New Technique Could Enable Chips with Thousands of Cores Researchers from MIT have unveiled the first fundamentally new approach to cache coherence in more than three decades,
a memory-management scheme that could help enable chips with thousands of cores. In a modern, multicore chip, every core or processor has its own small memory cache, where it stores frequently used data.
But the chip also has shared a larger cache, which all the cores can access. If one core tries to update data in the shared cache,
other cores working on the same data need to know. So the shared cache keeps a directory
of which cores have copies of which data. That directory takes up a significant chunk of memory:
In a 64-core chip, it might be 12 percent of the shared cache. And that percentage will only increase with the core count.
Envisioned chips with 128,256, or even 1, 000 cores will need a more efficient way of maintaining cache coherence.
At the International Conference on Parallel Architectures and Compilation Techniques in October, MIT researchers unveil the first fundamentally new approach to cache coherence in more than three decades.
Whereas with existing techniques, the directory memory allotment increases in direct proportion to the number of cores, with the new approach, it increases according to the logarithm of the number of cores.
In a 128-core chip that means that the new technique would require only one-third as much memory as its predecessor.
With Intel set to release a 72-core high-performance chip in the near future, that a more than hypothetical advantage.
But with a 256-core chip, the space savings rises to 80 percent, and with a 1, 000-core chip, 96 percent.
When multiple cores are simply reading data stored at the same location, there no problem.
Conflicts arise only when one of the cores needs to update the shared data. With a directory system, the chip looks up
which cores are working on that data and sends them messages invalidating their locally stored copies of it. irectories guarantee that
when a write happens, no stale copies of the data exist, says Xiangyao Yu, an MIT graduate student in electrical engineering and computer science and first author on the new paper. fter this write happens,
no read to the previous version should happen. So this write is ordered after all the previous reads in physical-time order. ime travelwhat Yu and his thesis advisor Srini Devadas,
the Edwin Sibley Webster Professor in MIT Department of Electrical engineering and Computer science realized was that the physical-time order of distributed computations doesn really matter,
so long as their logical-time order is preserved. That is core A can keep working away on a piece of data that core B has provided
since overwritten that the rest of the system treats core A work as having preceded core B. The ingenuity of Yu
and Devadasapproach is in finding a simple and efficient means of enforcing a global logical-time ordering. hat we do is we just assign time stamps to each operation,
and we make sure that all the operations follow that time stamp order, Yu says. With Yu and Devadassystem, each core has its own counter,
and each data item in memory has associated an counter, too. When a program launches, all the counters are set to zero.
When a core reads a piece of data, it takes out a easeon it, meaning that it increments the data item counter to,
say, 10. As long as the core internal counter doesn exceed 10, its copy of the data is valid.
The particular numbers don matter much; what matters is their relative value. When a core needs to overwrite the data,
however, it takes wnershipof it. Other cores can continue working on their locally stored copies of the data,
but if they want to extend their leases, they have to coordinate with the data item owner.
The core that doing the writing increments its internal counter to a value that higher than the last value of the data item counter.
Say, for instance, that cores A through D have all read the same data, setting their internal counters to 1
and incrementing the data counter to 10. Core E needs to overwrite the data so it takes ownership of it
and sets its internal counter to 11. Its internal counter now designates it as operating at a later logical time than the other cores:
Theye way back at 1, and it ahead at 11. The idea of leaping forward in time is
what gives the system its name Tardis, after the time-traveling spaceship of The british science fiction hero Dr. Who.
Now, if core A tries to take out a new lease on the data, it will find it owned by core E, to
which it sends a message. Core E writes the data back to the shared cache,
and core A reads it, incrementing its internal counter to 11 or higher. Unexplored potentialin addition to saving space in memory
Tardis also eliminates the need to broadcast invalidation messages to all the cores that are sharing a data item.
In massively multicore chips, Yu says, this could lead to performance improvements as well. e didn see performance gains from that in these experiments,
Yu says. ut that may depend on the benchmarksthe industry-standard programs on which Yu and Devadas tested Tardis. heye highly optimized,
so maybe they already removed this bottleneck, Yu says. here have been other people who have looked at this sort of lease idea,
says Christopher Hughes, a principal engineer at Intel Labs, ut at least to my knowledge, they tend to use physical time.
you can use this data for, say, 100 cycles, and I guarantee that nobody else is going to touch it in that amount of time.
because if somebody else immediately afterward wants to change the data, then theye got to wait 100 cycles before they can do so.
Simultaneously, the cost of 3-D printers has fallen sufficiently to make them household consumer items.
Now a team of MIT researchers has opened up a new frontier in 3-D printing:
From the discovery of core-forming process for bead-making in ancient Egypt, through the invention of the metal blow pipe during Roman times, to the modern industrial Pilkington process for making large-scale flat glass;
Like other 3-D printers now on the market, the device can print designs created in a computer-assisted design program,
producing a finished product with little human intervention. In the present version molten glass is loaded into a hopper in the top of the device after being gathered from a conventional glassblowing kiln.

#New Memristors Could Usher in Bionic Brains Last month we saw researchers in the US push the envelope of nonvolatile memory devices based on resistance switching to the point where they are now capable of mimicking the neurons in the human brain.
The researchers believe that these nanoscale memory devices promise a future of artificial intelligence network that could enable a so-called bionic brain.
Nili suggests that one of the potential applications for these nano-memory devices could be in replicating the human brain outside of the human body.
#A Computer That Can Sniff out Septic Shock Dr. David Hagar treats dozens of patients each day at the intensive care unit at John Hopkins Hospital in Maryland.
A group of computer scientists at John Hopkins University partnered with Hagar, and created an algorithm that can predict septic shock

The computer system sifted through a dataset of over 16,000 patient electronic health records, which includes a historical profile of blood pressure, heart rate,
The algorithm combined 27 of the most common measurements used to diagnose septic shock and generated a targeted real-time warning score,
One hurdle that needs to be overcome is that electronic health data can be challenging to work with,
explains the study lead computer engineer, Suchi Saria. Part of the difficulty is that there may be systematic bias in the medical information recorded.
These cases hurt the algorithm performance. Current computerized clinical decision support (CDS) models that utilize electronic health records do not account for this kind of censored information.
Saria and her team address this problem by modifying pattern recognition algorithms so the computer can avoid mistaking high-risk patients for low-risk ones.
This computer system can be tailored to many different medical conditions including acute lung injury, pneumonia, and post-rehabilitation illnesses like neuropathy. e are at a very exciting time,
and more data is being collected on the electronic health records, and now our algorithms are reaching a point where they can be a real aid to clinicians. t

#3-D Printing Software Turns Heart Scans into Surgical Models A new 3-D printing system can transform medical scans of a patient heart into a physical models that help
The efficient system relies on a computer algorithm that requires just a pinch of human guidance to figure out a patient heart structure from MRI scans.
The new software developed by MIT and the Boston Children Hospital, can correctly identify an individual heart anatomical structures by following the lead of a human expert who interprets a small patch equivalent to just one-ninth of the area of each cross section, according to an MIT press release.
and allowing the computer algorithm to infer the rest of the patient heart structure across the rest of the MRI scan 200 cross sections.
The software results were in agreement with human experts interpreting all 200 cross sections 90 percent of the time.
said Polina Golland, a professor of electrical engineering and computer science at MIT and leader of the project,
But the new software from a team led by Danielle Pace, an MIT graduate student in electrical engineering and computer science, managed to create a fairly accurate digital 3-D model of each patient heart in just an hour.
The 3-D printing process takes several additional hours. The researchers plan to report on their system at the International Conference on Medical Image Computing and Computer Assisted Intervention in October.
They hope to improve the software accuracy by examining patches that appear in several MRI cross sections.
Seven cardiac surgeons at Boston Children Hospital will also test the usefulness of 3-D printed heart models in a clinical study this fall.

pediatricians explained how hardware and software specialized for genetic analysis can provide such fast and lifesaving information.
The key piece of technology: A processor from the company Edico Genome that designed to handle the big data of genetics.
Lead researcher Stephen Kingsmore, a pediatrician and genomics expert at Children Mercy Hospital in Kansas city, explains that doctors typically run targeted genetic tests for specific diseases
Using Edico Genome DRAGEN processor, the researchers got this step down from 15 hours to 40 minutes.
After that, Kingsmore team used in-house software to search through the mutations for those associated with a disease that matched the baby symptoms.
noting that Children Mercy is going to make its software packages available as freeware by the end of the year.
The DRAGEN processor delivered its critical speed gains to the hospital servers thanks to its architecture,
which is designed to deal with genomic data, says Pieter van Rooyen, CEO of Edico Genome.
The data comes from the sequencing machine in a particular file format, which is streamed efficiently through the chip without caching,
Its algorithms are tailor-made to identify genetic mutations, and while these identification processes are ticking along the data is constantly being compressed
